Re: PVA size concentration for gum printing

[Paul Viapiano <viapiano@pacbell.net>]

Judy...others beat me to it...Fusion 4000 dry mount tisuue used in a Seal 
press. Holds it on there through all the development cycles, to take it off 
you heat to slightly higher temps in the press and gently tease it off. He 
dry mounts the finished print to another sheet of Fab...

John, the article does not say that he sizes the paper. It does say that he 
experimented with preshrink and resizing, but then started using the 
aluminum sheets, a method devised by Dick Sullivan.

I'm pretty sure he does not size...and I'm pretty sure Fab will hold pigment 
integrity through 3 water cycles, that is if pigment ratios aren't super 
high or using blacks or using forced development. But hey, what do I know? 
Just some thoughts based on limited experience...
